Patent DE-4009293-A1 (DE)
Inventor: NEUBAUER LUTZ DR ING
IPC: B41J17/32
Filed: 1990-03-20
Abstract: If several successive colour-application operations are to be carried out on a sheet of paper, the sheet is fed from the sheet output point of a pressure-applying element through a sheet feed channel with a curved turn-round zone back to the sheet input point of the pressure-applying element, and a high sheet-positioning precision if necessary, in order to obtain high-quality results. In order to ensure the precise alignment of the repeatedly refed sheet (11), the invention calls for the sheet (11) to be guided, by means of a raised area (60) on the concave surface (42) of the sheet turn-round zone (35), so that it is tilted in stages at right angles to the direction of motion. Downstream of the raised area (60), a force is exerted on the sheet at right angles to the direction of motion of the sheet, the force aligning the sheet (11) with the edge of a sheet-guidance surface (100). Multicolor printing.

Title: Mains connection device for fluorescent lamp - has inverse regulator for prodn. of constant operating voltage, and electronic switch in series branch to load in series with diode
Inventor: MERTENS FERDINAND DIPL ING
IPC: H05B41/298
Filed: 1990-03-31
Abstract: The electronic switch (T) is controlled by a regulating circuit (12), which compares an actual signal (Uist) with a desired signal (URef), and corresp. alters the opening and/or closing times of the switch according to the signal deviation. The actual signal (Uist) corresponds to the operating voltage (UB). The actual signal corresp. to the operating voltage (UB) is obtained, with a voltage (U1) at the electronic switch (T) and the diode (D), from which a voltage signal (UX) is subtracted, which only corresponds to the supply voltage (UV) with an inserted fluorescent lamp (LL). The voltage signal (UX) is taken from an electrode connection (19) for the fluorescent lamp (LL), which lies at a voltage across the relevant lamp electrode (E2), and the fluorescent lamp removed is without voltage. USE/ADVANTAGE - With lamp removed or non functioning lamp, voltage at lamp connections has large safety distance to unsafe voltages.

Inventor: BLITTSTEIN-WILLINGER EVELINE D
IPC: A61K31/557
Filed: 1991-07-22
Abstract: The use of carbocycline derivs. (I) and their base salts and cyclodextrin clathrates for the treatment of psoriasis vulgaris is new. (I) is pref. iloprost, cicaprost, eptaloprost, beraprost or ciprostene. USE/ADVANTAGE - (I) are TNF-synthesis inhibitors and are pref. applied topically in conventional dosage forms contg. 20-40 mcg/g vehicle. Max. tolerated daily dose is 80-160 mcg. (I) are superior to monoclonal antibodies against TNF and are also active when used prophylactically. In an example, topical admin. of iloprost induced a dosage dependent erythema which remained after treatment. Histological tests showed a low degree cellular infiltration of macrophages and T-helper cells but no granulocytes, together with an interstitial oedema and vascular dilation in the corium. This returned to normal after a 7 day break in treatment, indicating that iloprost selectively promoted the release of T-cells from the blood vessel
